VALVE.

Original application filed April'll, 1918, Serial No. 228,029.

To all whom it may concern:

Be it known that I, KARL D. SMITH, citizen of the United States, residing at Battle Creek, county of Calhoun, State of Mlchigan, have invented certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates to improvements in valves.

This application is a division of my application filed April 11, 1918, Scrlal No. 228,029.

The main object of this invention 1s To provide an improved resilient valve means in an emulsifying machine and one which is simple and compact in its structure and arrangement of its parts.

Further objects, and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claim.

A structure which is a preferred embod1- ment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which Fig. I is an elevation of a structure embodying the features of my inventlon.

Fig. II is a detail view mainly in vertlcal section on line corresponding to line 2-2 of Fig. IV.

Fig. III is a detail view corresponding to that of Fig. II in which the valve and its spring is shown in section. i

Fig. IV is a transverse section on the line corresponding to line 4.4E of Fig. II.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, I provide a body member or casing 1,'having a chamber 2 therein, provided with a passage 3 and a discharge passage 4:.

The body 1 has a central seat or recess 5 for the valve seat member 6 which has a conical valve seat 7 at its upper end and a longitudinal bore.

Valve member 8 has a conical portion 9 ooacting with the conical seat and a reduced Divided and this application filed September Serial No. 411,507.

stem or guide portion which reciprocates in the valve seat member. Valve member 8 has a longitudinal passage 10 opening at its lower end and communicating with the. lateral passages 11, opening into the annular groove 12 at the base of the head or conical portion of the valve member.

The passage of the material through the machine is controlled by the valve and coacting seat. The valve is effectively guided through its limited movement and supported against lateral of canting movement by its stem portion with the valve seat member. The valve is adjusted and held in position by means of the differential screw mechanism, comprising members 13, 14 and 15.

The member 13 is threaded into the open end of the casing and in effect constituting a part of the casing and a bushing for the outer adjusting member 14, which is threaded into the member 13.

The inner adjusting member 15 is threaded into the adjusting member. 14 and coacts with the cap-spring on the valve head, the end of the valve member being concave at 17 to permit the cap-spring to yield.

The adjusting member 15 is provided with a conical point 18 engaging the center of the cap-spring as shown in Fig. III.

The adjusting member 15 is provided with lateral projecting lugs 19 which engage in slots 20 in the lower end of the bushing 13, preventing the turning of the adjusting member 15.

The outer adjusting member 1 1 is provided with a hand-wheel 21.

The spring 16 is'of such strength that it will yield only under Very high pressure. For example :In treating milk and cream it is usually passed through the machine under a pressure of from one to two thousand pounds. With this adjusting mechanism the valve may be very accurately and combination of a casing provided with inlet and outlet connections, a valve seat, a coaeting valve having a concave top and a cap of spring metal over said valve, and means for applying pressure to said cap whereby the valve is held'yielclingly in place as specified.

In witness whereof, I have hereunto set my hand, and seal in the presenceof two witnesses.
